Running the Numbers
I took the opportunity to run the numbers and this is what I get:
DSP to Length = 368 (200-300 is “cruising”)
Sail Area to DSP Ratio = 14.2 (Most boats are between 16-18)
Hull Speed = 6.05 kts
Velocity Ratio = 1.05 (under powered is less than 1)
LOA to Beam = 2.72 (“fine” is 3.5-4)
Capsize Risk = 1.99 (over 2 cannot compete in ocean races)
Comfort Ratio = 22.09 (This is in the range of racers, cruisers are 60+)
The LOA/Beam ratio indicated a little “tubbiness”, but probably is this way to accommodate an interior. To get a “fine” hull, you would need to decrease beam by a foot or more which would probably “loose” the cabin. Where you are getting killed is the relatively small rig (small sail area) in relationship to the displacement. This is going to be a slow boat. The capsize risk and comfort ratios are marginal again, due to the high DSP to length ratio and smaller hull form (length and DSP). So how did I do? What boat is this? A Pacific Seacraft?
Valiente, can you give me your racing boat’s data for comparison?
